Re: Parsing a string
Mike
I like the method Dave used in his DLI Relay Flow. ?The response is an eight-digit number, with 0 or 1 in each digit, depending on the relay status. ? Dave has a function to do a "logical and" for each digit to determine and outputs a true or false. ?Would this work for you? ? For example, if the second digit is 1, then the function "1 & 2" is true, because the binary of the second digit is 2**1 = 2 and 2 logical 2 is true. ?Likewise, for the third digit, 2**2 is 4 so the logical comparator is 4. Alan. WA9WUD And here is the function. ?Of course,var onmsg = { payload: msg.payload,topic:msg.topic }; var offmsg = { payload: msg.payload,topic:msg.topic };
========================= ?
var msg1 = { payload: msg.payload,topic:msg.topic };
var msg2 = { payload: msg.payload,topic:msg.topic };
var msg3 = { payload: msg.payload,topic:msg.topic };
var msg4 = { payload: msg.payload,topic:msg.topic };
var msg5 = { payload: msg.payload,topic:msg.topic };
var msg6 = { payload: msg.payload,topic:msg.topic };
var msg7 = { payload: msg.payload,topic:msg.topic };
var msg8 = { payload: msg.payload,topic:msg.topic };
?
?
//msg.payload=true;
onmsg.payload=true;
offmsg.payload=false;
?
if (msg.payload & ? 1) msg1.payload=true; else msg1.payload=false;
if (msg.payload & ? 2) msg2.payload=true; else msg2.payload=false;
if (msg.payload & ? 4) msg3.payload=true; else msg3.payload=false;
if (msg.payload & ? 8) msg4.payload=true; else msg4.payload=false;
